Some exemptions apply for single-family homes. For each tree removed, one or more replacement trees with total value equal to the removed tree must be planted on the same property. The city may require relocation instead of removal. Pruning is allowed without a permit if it does not endanger the tree's life. Emergency removals for safety hazards are exempt. A tree report may be required to verify value and condition.
